Simplifying 7r + 3(7 + -1r) = (r + 4) 7r + (7 * 3 + -1r * 3) = (r + 4) 7r + (21 + -3r) = (r + 4) Reorder the terms: 21 + 7r + -3r = (r + 4) Combine like terms: 7r + -3r = 4r 21 + 4r = (r + 4) Reorder the terms: 21 + 4r = (4 + r) Remove parenthesis around (4 + r) 21 + 4r = 4 + r Solving 21 + 4r = 4 + r Solving for variable 'r'. Move all terms containing r to the left, all other terms to the right. Add '-1r' to each side of the equation. 21 + 4r + -1r = 4 + r + -1r Combine like terms: 4r + -1r = 3r 21 + 3r = 4 + r + -1r Combine like terms: r + -1r = 0 21 + 3r = 4 + 0 21 + 3r = 4 Add '-21' to each side of the equation. 21 + -21 + 3r = 4 + -21 Combine like terms: 21 + -21 = 0 0 + 3r = 4 + -21 3r = 4 + -21 Combine like terms: 4 + -21 = -17 3r = -17 Divide each side by '3'. r = -5.666666667 Simplifying r = -5.666666667
